Sharnw - yes, that will be your temp. My bbt saves the last temp recorded when turning it on. Pretty helpful.
Liz - bringing a child into the world is a big thing. Im not one to judge, but looks like you need to seriously think things through. It's not like he can just say hey, I change my mind about being a father or vice versa. Once it's here your the one that's life changes the most. As ash said, being a single mother is not easy. It's. It fair for the child. If your on and off again, your simply not ready for a lifetime commitment of a child. Sorry for sounding mean, but the truth huts sometimes.
